You can put this solution on YOUR website!
The equation for y can be written as: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "15x + 10y = 400\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "==> 10y = 400 + 15x \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "==> y = (400/10) + (15/10)x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "==> y = 40 + 1.5x \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The graph of the above equation is: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"+graph%28+400%2C+400%2C+-35%2C+35%2C+-90%2C+90%2C+1.5x+%2B+40%29+\"
\n" ); document.write( "
\n" );
